In the present study, performance of mixed microbial anaerobic culture in treating synthetic strong wastewater containing different concentration of atrazine was evaluated (R-1). Studies were also conducted in two hybrid reactors (A-1 and A-2) with wood charcoal as adsorbing matrix along with microbes. All the reactors for the treatment of atrazine bearing wastewater were operated in sequential...

Metabolism of the herbicide 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine) was investigated in resistant corn (Zea mays L.) and sorghum (Sorghum vulgare Pers.), intermediately susceptible pea (Pisum sativum L.), and highly susceptible wheat (Triticum vulgare Vill.) and soybean (Glycine max Merril.). This study revealed that 2 possible pathways for atrazine metabolism exist in high...

The atrazine behaviour in soils when submitted to an electric field was studied and the applicability of the electrokinetic process in atrazine soil remediation was evaluated. Two polluted soils were used, respectively with and without atrazine residues, being the last one spiked. Four electrokinetic experiments were carried out at a laboratory scale. Determination of atrazine residues were per...

The aim of the present study was to investigate the effects of low dose of atrazine on reproductive system of male Wistar rats. 16 rats were divided into four groups of four animals each. Group I (nondiabetic) and group III (diabetic) animals served as controls that received safflower oil (300 μL/kg bw/day), respectively. Group II (nondiabetic) and group IV (diabetic) animals received atrazine ...

The uptake of atrazine by rice seedlings (Oryza sativa L.) through plant roots from nutrient solution was investigated in the presence and absence of Cd2+ over an exposure period of four weeks. It was found that both atrazine and Cd2+ were toxic to rice seedlings. Both shoot and root biomasses decreased when the seedlings were exposed to increasing atrazine or Cd2+ concentrations in nutrient so...

We examined the ability of a soil bacterium, Agrobacterium radiobacter J14a, to degrade the herbicide atrazine under a variety of cultural conditions, and we used this bacterium to increase the biodegradation of atrazine in soils from agricultural chemical distribution sites. J14a cells grown in nitrogen-free medium with citrate and sucrose as carbon sources mineralized 94% of 50 microgram of [...

BACKGROUND Enhanced atrazine degradation has been observed in agricultural soils from around the globe. Soils exhibiting enhanced atrazine degradation may be cross-adapted with other s-triazine herbicides, thereby reducing their control of sensitive weed species. The aims of this study were (1) to determine the field persistence of simazine in atrazine-adapted and non-adapted soils, (2) to comp...

The efficacy of Andrographis paniculata (AP) extract was studied on atrazine induced hepatic damage in rats. Ethanolic extract of AP (150mg/kg body weight) was found to protect the male wistar rats from hepato toxic action of atrazine as evidence by significant reduction in the level of lipid peroxidation and increased the antioxidant defense system activity in the atrazine intoxicated rats. Ho...

background: fish have been at high risk of atrazine toxicity. comparative atrazine toxicity on the tissues of clarias gariepinus is scanty. therefore, acute and chronic effects of atrazine on some biochemical parameters in clarias gariepinus were investigated in this study. methods: atrazine toxicity was determined by assessing the responses of glucose, protein, alanine aminotransferase (alt), ...
